GAS-BURNER HOLDER.

To allwhom it map concern:

Be it known that we, James A. KLAHRE and HENRY F. A. KLmNsonMmr, residents of J ohnstown, in the county of Cambria and State of Pennsylvania, have invented cer tain new and useful Improvements in Gas- Burner Holders, of which the following is a specification.

Our invention has relation to apparatus for use in handling gas burners such as the oxy-hydrogen and oxyacetylene gas burners employed to cut metal and in locally heating metal articles.

One objectof our invention is the provision of an articulate holder for gas burners havingnovel means whereby the burner is held and is manipulated to cause the flame emanating from the burner to travel in a single flat plane, and thereby sever the metal with a eleancut and narrow kerf.

Anotherobject of the invention is to provide a holder for gas burners having imroved means whereby the burner holder is detachably held in place while manipulat ing the burner and holder in the operation of the burner.

A. further object of our invention is the provision of an articulate burnerholder having the novel construction, arrangement and combination of parts shown 1n the drawings and to be more fully described hereinafter and particularly pointed out in the appended claims.

Referring now to the drawings forming part of this specification, Figure l'is an elevation showing a burner holder embodying our invention j and illustrating its application in holding a gas burner in position relative to "a street car rail. l

Fig. 2 is an elevation, at a right angle to in Fig. 1. a a r In the accompanying drawings, the numeral 2 designates an oxy-hydrogen torch or burner, of any approved construction, as applied for use and held in place on a girder track rail, 3 or other article, by means of a manuallymanipulated articulate burner holder embodying our invention. In the construction shown, the holder has a clamping shoe 4 provided with heels 5, 5 at the ends thereof, and each heel 5 has clamping faces 6, 6 and 7 on one side, and similarly formed clamping faces 8, 8

and 9 on the opposite side thereof, the faces Specification of Letters Patent.

being formed in this way to facilitate the attachment of the holder to the work to be operated upon. a

The shoe 4 has lugs or ears 10, 10 on one side, at or adjacent to the middle of the lengththereof, to which the end of one branch of the forked clamping arm 11 is pivotally connected by means of a pin 12. The outer end of each of the two other branches of this arm, which are oppositely curved, has a hand screw 13 by which the shoe is detachably fastened to the rail 3.

By reference to Fig. 1 it willbe seen that the faces 7 are in a plane at a right angle tothat of the faces 6, 6 and that the faces 9 are arranged in a similar manner with .respect to the faces 8, 8. When the shoe is clamped tothe rail head, the faces 7 or 9,

depending upon which are being used, automatically take a position at right, angles to the gage line 1 1 of the rail. u

Pivotally secured at one end to the end of one or the other of the heels 5 of the shoe, by means of a bolt 15, is a link or swinging arm 16 and the other end of the arm16 is pivotally connected by a bolt to one end of a second arm 17 The heels 5 are formed to permit attachment of the swinging arms to either end of the shoe. The other end of the arm 17 is pivotally connected by a bolt 15 to one end of a third arm 18. The articulated arms 16, 17, and 18 preferably are duplicates, so as to be interchangeable. The free end of the arm 18 is provided with clamping means whereby the torch or burner 2 is removably secured in operative position on the holder with the tip 2 of the burner in position to be moved in a direction parallel to i the cross sectional outline of the article operated upon. As shown the fastening includes a bolt 19 having a thumb nut 20 on its threaded end with a pair of washers 21, 21 between the nut 20 and end of the arm 18. The part of the bolt 19 extending through the arm 18 is larger in diameter than the part for the washers 21, and this enlarged portion is of such length that the bolt 19 will freely rotate in the hole in the arm 18 when the burner is tightly clamped in place between the washers 21. The abutting faces of the washers 21 preferably have transverse grooves or recesses 22 therein to receive the parts of the burner 2 clamped therebetween. The bolts 15 are like the bolt 19 in having the portion thereof adjacent to 'erated upon by the torch or burner.

the bolt head of larger diameter than the balance of the bolt body to enable the arms to be pivotally fastened together and freely swing relatively about the axis'of the bolt .as' is necessary in using the holder, this the other arm.

In the operation of our improved apparatus one or the other of the clamping screws 13 will c oact with the adjacent clamping faces on the heels 5 on one side or the other of the clamping shoe 4 to rigidly attach the burner holder in the desired position on the rail or other article to be op- The burner holder will then be in readiness for use.

j In usingthe apparatus the operator will move the burner to maintain the'flame issuing from the tip of the burner in cutting position with that part of the rail to which the burner is fastened. In moving the burner to maintain the burner in cutting position the swinging'arms 16, '17 and 18 of the burner holder compel the movement of the burner tip and flame in a single flat plane and in aplane at a right angle to the length of the rail 3. In this. way a straight cut is made in severing the rails, and the size of the kerf made by-the flame is maintained within the desired limits. r

The relative length of the arms and the fact that they are. all freely movable in parallel flat planes which are at right angles to the rail clamped by the burner holder enables the burner to be moved to the extent necessary to entirely sever a girder rail of the type shown.

The'advantages of our invention, which will be appreciated by those skilled in the art, arise from the arrangement of the burner holder in such manner as to guide the burner in a single flat plane and in this way eliminate irregularities in severing articles which-are unavoidable when the direction of I movement as well as movement of the burner is manually controlled by the operator. 1 The apparatus is simple and effective, and is easily kept in repair.

Many modifications in the construction and arrangement of the parts forming this invention may be made. The form of the clamping shoe may be changed to suit different varieties of work, and other changes may be made without departing from our inventionas defined in the appended claims.

We claim v 1. A gas, burner holder comprising at least three articulate holder arms adapted to be actuated manually, and clamping means pivotally mounted on opposite ends of said articulated arms adapted to attach the gas burner to work operated upon by the burner, said arms bemg pivotally connected for universal movement and to swing the burner in a single fiat plane when the attached burner is manipulated.

2. A. gas burner holder comprising articulate holder arms adapted to be actuated manually, means at one end of said articulated arms for attaching the gas burner to said arms, a work engaging shoe at the other end of said arms, and a clanu iing arm pivotally mounted on said shoe, said shoe and said arm coacting to attach said holder lo the work operated upon by the burner. said articulate arms being pivot-ally connccie! to swing the burner in a single flat plane when the gas burner is manipulated.

3. A gas burner holder comprising at least three holder arms pivotally secured to gather and arranged to be actuated manu ally, means at one end of said pivoted arms for attaching the gas burner to said arms. a work engaging Shoo at the other end of the arms, and a clamping arm pivotally moonled on said shoe. said shoe and said clamping arm coacting with said arms to attach the holder to work operated upon by the burner. said holder arms being adapted to swing the burner in a single flat plane when lllillllDlllating the gas burner. and said Shoo having means for alining the holder on the work.
